"dmesg" shows since some days the following lines permanently, if im connected
with a nx-session (kde) knemo also tells the whole time that connection now is here.
So the connection seems not to be interrupted completely, nx-session runs
without interrupt and a script from another machine tries every second a
socket-connection on ssh-port without messages.
But i think this should not be so:
